Types Of Earthquake
This is a list of different types of earthquake. A * Aftershock, a smaller earthquake that occurs ''after'' a previous large earthquake, in the same area of the main shock. B * Blind thrust earthquake, an earthquake which occurs along a thrust fault that does not show signs on the Earth's surface. C * Cryoseism, a seismic event that may be caused by a sudden cracking action in frozen soil or rock saturated with water or ice. D * Deep-focus earthquake, also called a plutonic earthquake, an earthquake with a depth exceeding . * Doublet earthquake, an earthquake that consists of at least two or more mainshocks of nearly identical magnitude, separated by a period of time. E * Earthquake swarm, events where a local area experiences sequences of many earthquakes striking in a relatively short period of time. F * Foreshock, an earthquake that occurs ''before'' a larger seismic event (the mainshock) and is related to it in both time and space. H * Harmonic tremor, a su ...

Aftershock
In seismology, an aftershock is a smaller earthquake that follows a larger earthquake, in Epicenter, the same area of the Mainshock, main shock, caused as the displaced Crust (geology), crust adjusts to the effects of the main shock. Large earthquakes can have hundreds to thousands of instrumentally detectable aftershocks, which steadily decrease in magnitude and frequency according to #Aftershock size and frequency with time, a consistent pattern. In some earthquakes the main rupture happens in two or more steps, resulting in multiple main shocks. These are known as doublet earthquakes, and in general can be distinguished from aftershocks in having similar magnitudes and nearly identical seismic waveforms. Distribution of aftershocks Most aftershocks are located over the full area of fault rupture and either occur along the fault plane itself or along other faults within the volume affected by the strain associated with the main shock. Typically, aftershocks are found up to a d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Texas A&M University Libraries
The Texas A&M University Libraries support the teaching, research, and outreach missions of Texas A&M University through leadership in acquiring, managing, and delivering information in an environment that fosters learning and inquiry. In particular, Texas A&M is nationally and internationally recognized for many research collections, including: * Engineering & Technology * Entomology * Military History * Nautical Archaeology * Naval Science * Oceanography & Hydrology * Range Livestock * Science * Science fiction * Transportation Contents and Services Contents The libraries house over 4.5 million print volumes, including nearly 124,000 serial titles, and over 5.5 million microform items. Holdings also include approximately 250,000 maps in the Maps & GIS Library, and over of archival and manuscript collections in the Cushing Memorial Library and Archives, including approximately 170,000 printed volumes, over 50,000 photographs, over 200 original works of art, hundreds of individ ...

Volcano Tectonic Earthquake
A volcano tectonic earthquake or volcano earthquake is caused by the movement of magma beneath the surface of the Earth. The movement results in pressure changes where the rock around the magma has a change in stress. At some point, this stress can cause the rock to break or move. This seismic activity is used by scientists to monitor volcanoes. The earthquakes may also be related to dike intrusion and/or occur as earthquake swarms. Usually they are characterised by high seismic frequency and lack the pattern of a main shock followed by a decaying aftershock distribution of fault related tectonic earthquakes. Cause of volcano tectonic earthquakes One possible scenario resulting in a possible volcano tectonic earthquake occurs in tectonic subduction zones. The compression of plates at these subduction zones forces the magma beneath them to move. Magma can not move through the newly compressed crust as easily. This means it tends to pool in magma chambers beneath the surface and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ScholarSpace
The Hamilton Library at the University of Hawaiʻi at Mānoa is the largest research library in the state of Hawaii. The Library serves as a key resource for the flagship Manoa campus (a land, sea and space grant institution) as well as the other University of Hawaiʻi system campuses. It was designed by George Hogan who designed numerous houses on the island including Plantation Estate which was used by Barack Obama as his Winter White House. Description Hamilton Library is located at the University of Hawaii at Mānoa, at 2550 McCarthy Mall. It is composed of a circulating research library combined with a non-lending research library system. As of June 2013, the Library has a full-time equivalent of 46 library faculty and 31 other professional staff, 58 support staff, and 46 student assistants. The collections contain 3,102,696 volumes, 2,353,143 microform units, of manuscripts and archives, 112,000 audiovisual items, 200,000 maps and 100,000 aerial photographs, over 150,0 ...

Tsunami Earthquake
In seismology, a tsunami earthquake is an earthquake which triggers a tsunami of significantly greater Seismic magnitude scales, magnitude, as measured by shorter-period seismic waves. The term was introduced by Japanese seismologist Hiroo Kanamori in 1972. Such events are a result of relatively slow Earthquake#Rupture dynamics, rupture velocities. They are particularly dangerous as a large tsunami may arrive at a coastline with little or no warning. Characteristics The distinguishing feature for a tsunami earthquake is that the release of seismic energy occurs at long periods (low frequencies) relative to typical tsunamigenic earthquakes. Earthquakes of this type do not generally show the peaks of seismic wave activity associated with ordinary events. A tsunami earthquake can be defined as an undersea earthquake for which the surface-wave magnitude Ms differs markedly from the moment magnitude scale, moment magnitude Mw, because the former is calculated from surface waves with a ...

Spectrum News
Spectrum News (formerly Time Warner Cable News) is the brand for a slate of United States cable news, cable news television channels that are owned by Charter Communications through its acquisition of Time Warner Cable in May 2016. Each of the 17 regional channels primarily focus on local news, weather and sports coverage in their given areas, in addition to national and international news stories. With the exception of NY1, Spectrum News Southern California, and the Spectrum News channel for Dallas-Fort Worth (which is available over-the-air and on competing cable companies by virtue of KAZD's must-carry status), all of the channels are available only via Charter-owned pay television in their respective markets, not appearing on Verizon FiOS, AT&T U-verse, DirecTV or Dish Network. In July 2022, Charter added all Spectrum News networks, including NY1, Bay News 9 and Spectrum News 13, News 13, to their Spectrum TV mobile and smart TV apps within the 2200s tier of channels, allowi ...

Strike-slip Earthquake
In geology, a fault is a planar fracture or discontinuity in a volume of rock across which there has been significant displacement as a result of rock-mass movements. Large faults within Earth's crust result from the action of plate tectonic forces, with the largest forming the boundaries between the plates, such as the megathrust faults of subduction zones or transform faults. Energy release associated with rapid movement on active faults is the cause of most earthquakes. Faults may also displace slowly, by aseismic creep. A ''fault plane'' is the plane that represents the fracture surface of a fault. A ''fault trace'' or ''fault line'' is a place where the fault can be seen or mapped on the surface. A fault trace is also the line commonly plotted on geological maps to represent a fault. A ''fault zone'' is a cluster of parallel faults. However, the term is also used for the zone of crushed rock along a single fault. Prolonged motion along closely spaced faults can blur the ...
